It made 100 million stateside and 300 million total. That's far less than most Dreamworks films like the Shrek series including Puss in Boots, Madagascar, Kung Fu Panda, How to Train Your Dragon, heck even Megamind was more popular.

Yet you don't really see cosplays from those, barring a few Hiccups/Astrids/Fionas. You see Jack Frost because it's an easy/cheap to make and comfortable costume.

Adventure Time, My Little Pony, Disney Princesses, and the always present and hardly ever THAT impressive Sailor Moon cosplays.
But please, NO MORE PANTY AND STOCKINGS! There were so many last year that it almost rivaled Black Butler (Kuroshitsuji)'s debut a few years back.

Homestuck (Still. . .)
Doctor Who (It's easy and as popular as ever)
My Little Pony (Groan. . .)
Sailor Moon (With the 2013 series I think we'll be seeing A LOT more Sailor Scouts then the handful we see every con. Nice to see some Anime cosplay at the Anime Cons for a change)

At Katsucon this past weekend, Homestuck held the largest meet-up I have ever seen. Must have been several hundreds of them, and there were at least a dozen in my immediate area that did not attend. You could not turn your head without spotting another few.

Tons of default Kirito's and Asuna's (SAO), Adventure Time, and Black Butler.
